VENT-AXIA INTEGRA PLUS – HEAT RECOVERY VENTILATION UNIT
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Read the following instructions in conjunction with the illustrations before commencing installation.
Product Description
The INTEGRA PLUS is a loft/ceiling mounted heat recovery ventilation unit for domestic and commercial
applications. It is designed for connection to 150mm-diameter insulated flexible or rigid ventilation ducting.
The unit’s two fans and heat exchanger arrangement simultaneously supply and extract air while transferring heat
from the stale exhaust airflow to the fresh intake airflow. This provides up to 70% heat recovery from the stale
extracted air.
Separation of the exhaust airflow and intake airflow is maintained throughout the unit.
The fan motors have maintenance free self lubricating long life bearings and are fitted with thermal overload
protection, which in the event of a fault causing a motor to overheat will cut off the electrical supply to that motor.
The electrical power consumption of the unit is 425W when running at maximum speed from a 230V supply.
